Emerson's Rosemount CX2100 in-situ oxygen analyzer provides critical information to optimize combustion processes and help manufacturers meet emissions standards, reduce energy costs and improve safety. Analyzers of this type are used in a variety of industries, including power and utilities, chemical and petrochemical, pulp and paper, oil extraction and refining, metals processing and mining.
According to Emerson, extractive oxygen analyzers for combustion processes are generally difficult to install, commission and maintain, which makes it difficult to optimize these processes. In contrast, the CX2100 is said to be easy to install and comes with a wide range of accessories for installation in various process conditions, such as high temperatures and high particulate or sulphur contamination. The transmitter can be mounted up to 91 meters (300 feet) away from the probe, which further simplifies installation and is particularly important for personnel safety.
Commissioning the CX2100 is simplified by the menu navigation of the user interface, which is available in seven languages. The interface has capacitive touch switches, offers a wide range of customization options and is housed in a robust metal casing to protect the internal electronics. The guided installation can also be carried out via a remote host such as a control or asset management system.
The sensor's quick connect/disconnect function facilitates maintenance. Replacement is accelerated by the fact that no rewiring is required. Ceramic or Hastelloy filters, which protect the sensor from wear even at high temperatures, ensure a long service life. These filters can be replaced at the point of use.
Automatic calibration and calibration check functions regularly measure the accuracy of the analyzer. This gives technicians more time for more important tasks and increases safety by ensuring that the analyzer does not exceed or fall below the calibration limits. Safety is further enhanced by a flame safety interlock, which automatically switches off the heating of the sensor as soon as a burner failure is reported.
